IMPROVEMENT IN DRAWING APPARATUS FOR PORTABLE VESSELS.

Specification forming part of LettersPatent No. 34,554, dated February25, 1862.

To all whom it may concern:

Be it known that I, J LAWSON TREAT, of No. 90 Fulton street, in thecity, county, and State of New York, have invented a new and usefulImprovement in the Manner of Draw ing Liquids from Portable VesselsDesigned Especially for Table Use; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, making a part of thisspecification, in whichy Figure l is a vertical section of my invention;and Fig. 2 is a horizontal section taken ii: the line w of Fig. l, withthe top removed.

Similar letters of reference indicate corresponding parts in the twofigures.

The object of this invention is to obtain asimple means of drawing tea,coee, water, and other liquids from portable vessels without having todraw from a faucet or to raise or tilt the vessel; and it consists inhaving an inner shell which is open at the bottom and provided with anopening and valvein the top suspended within the vessel from the lid orcover of the same byahelical or coil spring, the iiquor being drawn fromthe vessel by simply depressing a short spindle, which, first closingthe opening in' the top of the shell, forces it down, and simultaneouslytherewith causes the liquor to discharge through the spout` as will behereinafter fully explained.

To enable others skilled in the art to fully understand and construct myinvention, I will proceed to describe it. l

A rfpresents a liquid-vessel of cylindrical form, made of Britanniaware, or it may be of silver, tin, or of any other suitable compositionmetal, and in any of the Ways in which similar articles of like metalsare usually made. This vessel at its lower end is provided with anannular flaring flange d for it to rest upon, which flange may be plainor ornamented, as may be desired.

Attached or formed on one side of the vessel near its upper end is aspout b, through which the liquor is drawn from the vessel. Said spoutmay represent the head and neck of a water-fowl, as in the accompanying'illustration, or it may be made of any suitable shape.

Fitted loosely within the vessel A is another vessel or shell B, whichis about three-quarters (more or less) of the entire length of thevessel A, and is open at the bottom and closed at the top with theexception of a small opening c, for the purpose hereinafter to beexplained. This shell is suspended within the vessel A by a wire springd in helical form, attached at its lower end to an annular flange e,which is attached to the top of the shell,

and atits upper end said spring is attached to a screw-cap f,whichscrews onto another cap g, supported on the hood O by a Harige formed onits periphery. The hood O sets in the top of the vessel A and rests atits lower edge on a square shoulder formed in the inner periphery of thevessel. The iiange e, which is attached to the top of the shell bysolder or otherwise, has an opening made through it on one side, inwhich one end of a short lever c', fulcrurned to the shell inside of theRange, plays up and down, said lever having suspended from its outer enda weighted valve j, which is on the inside of the shell, and is for thepurpose of closing the opening in the top of the same when it is desiredto draw liquor from the vessel. The inner end of this short lever has acavity formed in it, in which the lower end of the short spindle krests. This spindle is fitted so as to play freely up and down in asleevel, attached to the under side of the cap g, and near its lower endit is provided with a collar to prevent it from being withdrawn from thesleeve and to lift the shell out of the vessel A when itis desired tolill the same.

.The spindle at its upper end is furnished with a knob or button D, uponwhich the pressure of the hand is exerted to depress the spindle, and byit the shell when it is desired to draw liquor from the vessel. Vhen thevessel is to be filled with any liquor, the shell has first to bewithdrawn, which is effected by simply taking hold of the spindleandlifting the hood, cap, and shell all together. The vessel beingfilled, the shell is returned to its place, the hood resting at itsbottom edge on the square shoulder in the top of the vessel, ashereinbefore described. The spring d in its normal condition is in acompressed state, and in that state sustains the shell in the vessel inan elevated position. The valve j, when the shell is in its highestposition and normal state in the vessel, is keptopen by itsgrax-'itating tendency, allowing a free circulation of air in the shell.By placingthe'h'a'nd upon lthe button of the spindle and pressing thespindle down it first closes the valve and then forces the shell down.The aircontained in the shell above the liquor having no means of escapeacts upon the surface of the liquor, causing it as the spindle isdepressed to rise in the space surrounding the shell and between itandthe inner periphery of the vessel, and discharge through the spoutnear the top of the vessel. By removing the hand from the spindle thehelical spring retracts the shell, and when in its highest position theWeighted valve opens, as before described, and allows the air to rushinto the shell to supply the place of the liquor drawn o.

This invention is designed more especially for the use of families totake the place of the usual tea and coifee urns from Which the liquor isdrawn oft through a faucet, and also of pitchers and similar vesselswhich have to be raised and tilted to draw from, being more convenientthan either and less liable to get' out of order than the two former.The liquor being drawn oft' near the top of the vessel, there is nochance for any to escape through carelessness or neglect-a serious objection to all vessels which have faucets to dravsr from.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The vessel A, having an inner shell B fitted when arranged to operate inthe manner sub-- stantially as herein described.
